利用木耳菌糠栽培元蘑技术的研究

Fungus Chaff Study on Cultivation Technology of Hohenbuehelia serotina

为了解决黑龙江省每年大量木耳菌糠得不到有效利用的实际问题,并积极探索元蘑代料栽培的新技术,以传统栽培种配方CK为对照,以12%的浓度梯度逐渐用菌糠代替木屑设计6个栽培种配方,等量接种生长状况一致的原种,在相同的条件下发菌与出菇。通过采用测定元蘑菌丝的生长势、满袋天数、原基形成时间、成菇状况、子实体的长势及生物学转化效率的方法,研究了栽培料中不同菌糠浓度对元蘑生长周期、生物学效率以及品质的影响。结果表明:栽培种配方为木耳菌糠36%、木屑44%、麦麸17%、黄豆粉1%、玉米面1%、碳酸钙1%,适宜元蘑生长。其菌丝生长浓密健壮,生物学转化效率为81.96%,比对照高出1.74%,试验证明了利用木耳菌糠栽培元蘑是可行的。

In order to solve the problem that so much waste materials of Auricularia auricula is not effectively used in Heilongjiang Province, the author actively explored new technologies for Hohenbuehelia serotina cultivation, with the traditional formula CK cultivated species as control, 12% germ bran in place of chips designed for concentration gradient gradually 6 eultivar formula, equal growth of inoculated seed, bacteria and mushrooms were cultivated under the same conditions. By determination of pleurotus eitrinopileatus myeelium growth potential, full bag, primordia formation time, conditions, fruiting of pleurotus and conversion efficiency of biological growth method, examined the effects of different concentration of germ bran in cultivation mushroom growth cycles, biological effects of efficiency and quality. Results indicated that, when the cultivated species composition contained 36% fungus chaff, 44% sawdust, 17% wheat middlings, 1% soybean flour, 1% corn flour and 1% calcium carbonate, Hohenbuehelia serotina grew well. Hyphae grew thick and strong, biological conversion efficiency of 81.96%, 1.74% higher than the control, experiment proved that a fungus germ bran cultivated mushroom was feasible.
